To allpersons to whom these presents may como:

-Be it known that I, Isaac P. RICHARDS, ot' Whitinsvillc, ofthe county of Worcester and State of Massachusetts, have invented a new and useful Improvement iii the'Bolsters oi' the Spi'idlc of .Spinning Frames or Machines; and do hereby declare the saine to he fully described in the following speeitication and represented in the accompanyil'ig dra-wing, of winch-- Figure 1 is a top view, and l Figure 2 a vertical section of a bolster as improved; by me, the improvement having reference to the bol-- sier constituting the subject ot' Letters Patent No. 92,647, dated July 13, 1869, and granted to lne. 'A

My patented invention consisted in, constructing conical, or wilhan inclination to the axis of the holster, that wall o' part of the oil-1eservoir of Vthe bolster which is next to the spindle bearing.

' .In carrying ontmy 4present invention, I have combined withv Vthe bolster so made an annular guard or cietiector, to be arranged at the top of the oil-reservoir, and to extend from the outer edge thereof nearly to and around the bolster, cone, o r inclined part, as described, the 4purposes of such guard being to pre rent dust and fibers from' getting into the oil-reservoir; also to prevent the. oil t'roinbeing thrown ont of the reseryoir hy centrifugal force. or otherwise; also to prevent the cloth or waste usedl in cleaning the spinthe oil-reservoir and about the spindle bearing a.

The annnlargnard is shown at. B. It may besonaewhat varied in form from what is shown, without changing it in principle or opeiation, that it may he more or less concave or convex, and, it' desirable, it'

may have one or more apertures, d, through it, for the pnrpose'ot enabling oil to be forced' through it into the reservoir. i

.It serves as a shield to the cone, and prevents filaments from getting upon it and interrupting its effective operation. I t will he observed thatit is enti-rely insulated from the cone, or does not touch it, and circumscrihes the spindlewlien in the hearing.

I claim- The combination of the annulaLgard `llwith 'the bolster, made with the oil-elevating cone arranged in its oil-reservoir,` as set forth.
